I run a system with ZFS and 2GB RAM (though only 40GB disk) without any major tuning (AFAIR, I've only adjusted vfs.zfs.arc_max). That said, more RAM would be better. >Definitely go with a 64-bit install. Even with less than 4 GB of RAM, >you'll benefit from the large kmem size and better auto-tuning. I'd strongly recommend against running ZFS on i386 as anything other than an experiment. --=20 Peter Jeremy --d6Gm4EdcadzBjdND Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) iEYEARECAAYFAk9MjtIACgkQ/opHv/APuIcJOwCePTlCTPdUmnSSmVPJPAlzcJYN 0xwAn0AVrIp6etH/fNzxQHmALZdxYUd+ =/L4X -----END PGP SIGNATURE----- --d6Gm4EdcadzBjdND--
